Matúš Krčmár, Jaromír Šimonek, Ivan Vasiľovský

Acta Gymnica 2015, 45(3):103-111 | 10.5507/ag.2015.016

Background: High muscular power output is required in many athletic endeavors in order for success to be achieved. In the scientific community postactivation potentiation and its effect on performance are often discussed. There are many studies where the effect of resistance exercise on motor performance (such as vertical jump performance and running speed) has been investigated but only a few of them studied power output. Objective: The purpose of this study was to determine the acute responses to a 2 set loaded half-squat jumps and 2 set loaded back half-squat protocols designed to induce the acute maximum average power output during...

Acta Gymnica 2015, 45(3):113-119 | 10.5507/ag.2015.017

Background: Small-sided games belong to specific training where exercise intensity can be manipulated mainly by modifying external factors. To ensure suitable usage of small-sided games in practice, we have to know the variables, which could influence internal responses and external loads. Objective: The purpose of this work is to determine the influence of opponents of different levels on internal response and external load during a 4-a-side soccer game. Methods: Twenty physical education and soccer coaching students (age 22.53 ± 1.02 years; body mass index 20.83 ± 2.13 kg ⋅ m-2; peak heart...

Somatic characteristics in relation to meeting recommended physical activity in overweight and obese women aged 30-60 years

Tereza Sofková, Miroslava Přidalová

Acta Gymnica 2015, 45(3):121-128 | 10.5507/ag.2015.013

Background: Physical activity (PA) can provide health benefits and thus reduce the risk of complications from obesity and improve mental well-being. We consider body composition as an acceptable indicator of the functional condition of the body. Aims: Our research objective was to analyse selected body composition fractions in relation to meeting recommended PA in overweight and obese women. Methods: 221 women participated in our study, divided in two age groups: 30 to 44.9 years (Maturus I, n = 118) and 45 to 60 years (Maturus II, n = 103). Each age group was further differentiated by sub-groups (adequate and inadequate...

The differences of movement between children at risk of developmental coordination disorder and those not at risk

Adrián Agricola, Rudolf Psotta, Reza Abdollahipour, Miriam Palomo Nieto

Acta Gymnica 2015, 45(3):129-138 | 10.5507/ag.2015.007

Background: Developmental coordination disorder (DCD) is a syndrome unexplained by medical condition, which is marked by defects in the development of motor coordination. Children with this impairment are more dependent on visual information to perform movements than their typically developing (TD) peers. Objective: The main aim of the research was to create a checklist for the evaluation of the head and limb movement while walking. After that, based on this tool, to find differences in the movement of various body segments in children at risk of DCD (DCDr) compared to typically developing children under different visual conditions....

Pupils with sensory disabilities in physical education classes: Attitudes and preferences

Petra Kurková, Dagmar Nemček, Jela Labudová

Acta Gymnica 2015, 45(3):139-145 | 10.5507/ag.2015.015

Background: The key factor that affects the success of shaping positive attitudes towards regular life-long performance of physical activity (PA) is the pupils' level of inner motivation. This is influenced, among other things, by their family background, the educational institution that they attend and the educator's competencies. Objective: The purpose of this study was to describe and analyse the attitudes among pupils with sensory disabilities in physical education (PE) classes. A partial objective was to compare the preferences for various PA by pupils with sensory disabilities in PE classes. Method: A non-standardized questionnaire was used to...

Psychomotor development differences between Czech adolescents from orphanages and adolescents from majority society

Jakub Holický, Jakub Kokštejn, Martin Musálek

Acta Gymnica 2015, 45(3):147-154 | 10.5507/ag.2015.018

Background: The results of foreign studies have shown that psychomotor development of adolescents from orphanages falls significantly behind common developmental norms. In the Czech Republic, there is a lack of evidence of this issue despite the fact that some experts emphasize the possible defects of institutional care in the Czech Republic.Objective: The purpose of the study was to compare the level of psychomotor development of 13 year old adolescents from orphanages located in Prague and their counterparts from majority society. Methods: Psychomotor development of adolescents was tested with the complete form of the Bruininks-Oseretsky Test of...
